For all users, we recommend placing our sound machines (including Rohm, Hushh, and Dohm models) at least three feet (3') away from the sleeper’s head. This is mostly to allow the sound to fill the room for the best possible sound masking, but it also serves to ensure that the sound will not be too loud. At a distance of 6.5 ft, we measure the dB level of the Dohm’s loudest setting at 52.5 dB and of our lowest setting at 41.5 dBA. For comparison sake, know that a quiet whisper measures 40 dB and rainfall measures 50dB.
